Ah, thank you. Not dovecot at all, makes sense. I was sending to root
because of a problem with keychain preventing usage of the mail
command for users:
http://ubuntuforums.org/showthread.php?t=2065461
Anyhow, that's fixed so that I can now use the mail command as a
mortal, as you put it. I think I'm on my way, and that this is a
postfix and not dovecot problem. The mail doesn't arrive, but the log
shows as delivered (I think) and then removed for some reason:

Judging from your previous post where deliver tried to write to
/root/Maildir/, I suppose your mail will be found in
~thufir/Maildir/new/ .
Now Postfix is fine, Dovecot seems to be fine also. Your remaining
issue is with mail. If it's old BSD mailx, that is not very
configurable. Consider other choices, such as mutt, alpine, or
Heirloom mailx.
